"The models we discuss belong to the class of two-variable systems with one delay for which appropriate delay stabilizes an unstable steady state. We formulate a theorem and prove that stabilization takes place in our case. We conclude that considerable (meaning large enough, but not too large) values of time delay involved in the model can stabilize love affairs dynamics

Alan Cooper and the Goal Directed Design Process The heart of the problem, he concludes, is that the people responsible for developing software products don’t know precisely what constitutes a good product. It follows that they also do not know what processes lead to a good product. In short, they are operating by trial and error, with outcomes like customer satisfaction achieved by little more than blind luck. By Hugh Dubberly, first published AIGA GAIN Journal, 2001

"Systems thinking (PDF) is the process of understanding how things influence one another within a whole...Systems Thinking has been defined as an approach to problem solving, by viewing 'problems' as parts of an overall system, rather than reacting to specific part, outcomes or events and potentially contributing to further development of unintended consequences."

A Pattern Language explores the living structure in good and bad buildings, human artifacts, and natural systems, discussing the presence of the same living order in all systems. [Christopher] Alexander proposes that the living order depends on features which make a close connection with the human self. The quality of works of art, artifacts, and buildings is defined not merely in terms of living structure, but also in their capacity to affect human growth and human well-being.

Fareed Zakaria: Are America's Best Days Behind Us?
- "We have an Electoral College that no one understands and a Senate that doesn't work, with rules and traditions that allow a single Senator to obstruct democracy without even explaining why. We have a crazy-quilt patchwork of towns, municipalities and states with overlapping authority, bureaucracies and resulting waste. We have a political system geared toward ceaseless fundraising and pandering to the interests of the present with no ability to plan, invest or build for the future. And if one mentions any of this, why, one is being unpatriotic, because we have the perfect system of government, handed down to us by demigods who walked the earth in the late 18th century and who serve as models for us today and forever. America's founders would have been profoundly annoyed by this kind of unreflective ancestor worship." [for

Out of thin air?
"Have you ever said something like 'Let me buy you a beer next week'? I'm sure you have. We all issue promises of this sort. And we frequently use such promises as a form of currency... I have just described a simple credit exchange. Societies rely heavily on promising-making and promise-keeping. It is the foundation of all financial markets. I'd like to point out something about the promises you make. They are made 'out of thin air.' " [more inside]

Trash cans, landfills, and incinerators. Erasure, deletion, and obsolescence. These words could describe what has happened to the various building blocks of the video game industry in countries around the world. These building blocks consist of video game source code, the actual computer hardware used to create a particular video game, level layout diagrams, character designs, production documents, marketing material, and more.
These are just some elements of game creation that are gone -- never to be seen again. These elements make up the home console, handheld, PC and arcade games we've played. The only remnant of a particular game may be its name, or its final published version, since the possibility exists that no other physical copy of its creation remains.
As a community of video game developers, publishers, and players, we must begin asking ourselves some difficult but inevitable questions. Some believe there is no point in preserving a video game, arguing that games are short-term entertainment, while others disagree with this statement entirely, believing the industry is in a preservation crisis.

It's all one's and zero's eh?
The complex patterns of the natural world often turn out to be governed by relatively simple mathematical relationships. A seashell grows at a rate proportional to its size, resulting in a delicate spiral. The gossamer network of galaxies results from the simple interplay between cosmic expansion and the force of gravity over a wide range of scales. As our catalogue of natural phenomena has grown more complete, more and more scientists have begun to look for interesting patterns in human society.

Me Ta Fi L Te R = 318514
The Phonetic Numerals system provides a convenient way to remember long strings of numbers. It's really simple: the system replaces the numbers 0-9 with the symbols
(the strikethoughs indicate the difference between the symbol and the letter that it takes the place of). Take a long number (3.1415926, for example), convert it into Phonetic Numerals
), then come up with a phrase using those letters (
ob.) See? Easy!

Dancing with Systems: What to do when systems resist change.
Is an excerpt from the late Systems Theorist and Enviromentalist Donella Meadow's unfinished last book. There is beautiful information here. If you are confused and wondering about some of the ideas that has infused the world-wide peace, enviromental, social justice and anti-globalization movements (That is of course Globalization as defined by the Washington Consensus policies) you would be very hard pressed to find a better place to start.
Here are points in the essay.
Listen to the wisdom of the system.
Expose your mental models to the open air.
Stay humble. Stay a learner.
Honor and protect information.
Locate responsibility in the system.
Make feedback policies for feedback systems.
Pay attention to what is important, not just what is quantifiable.
Go for the good of the whole.
Expand time horizons.
Expand thought horizons.
Expand the boundary of caring.
Hold fast to the goal of goodness.

Counting in base-14.
"Just because we
use a decimal system doesn't mean everyone does. "The teseradecimal lifestyle is thus not just a way of life. It is not only a method of regulating marriage, birth, succession, and other aspects of village life. It is also a theory of history where genesis, finality, and apocalypse are laid out on the space between the pinky and the nose."
Alex Golub illuminates the counting system of the Ipili tribe of Papua New Guinea, in response to much discussion of the ethnomathmatics
